The proposed algorithm achieves overall 97% detection accuracy against various steganography methods.ĭ. Results are further validated using 10 fold cross validation process. Stego images are generated using widely available stego tools for two standard image databases: CorelDraw and BSDS500. The proposed algorithm is tested against steganography methods like F5, Outguess and LSB based method. These reduced dimensional 15-D feature vector is used to train SVM classifier with RBF kernel. Fisher criterion and ANOVA test are applied to evaluate the combined feature vector score and then only those features are selected which are found sensitive in both feature selection methods. Statistical features extracted from wavelet subbands and binary similarity patterns extracted from DCT of an image are merged to make combined feature set. The goal of this paper is to develop a reduced dimensional merged feature set for universal image steganalysis using Fisher Criterion and ANOVA techniques. Effectiveness of any Image Steganalysis algorithm depends on feature selection and feature reduction. Who do you think is in charge of their bodies?" Lu Siyuan said: "You are still too naive.Unethical uses of data hiding methods have made Image Steganalysis a very important area of research work in the field of Digital Investigations. "Zhou Siyu has been sold seven or eight times. Yang Xiaoxi's jaw dropped in shock, "Isn't she? Is she a pig? She has four children in a row, doesn't she take her body seriously?" It is the norm that children are born one after another. Zhou Siyu and Zhao Xinlan were both good looking, and petite and lovely people naturally became sweet when they arrived there, and there was no family planning there. Shen Mianmian was a little surprised, but after thinking about the situation over there, Shen Mianmian was not surprised. If you have one, do you know how many Zhao Xinlan and Zhou Siyu have?"īefore waiting for the two to speak, he added: "Six, both of them have given birth to six children, and one of them is pregnant with one." "It really belongs to you, so I guessed it right away." Lu Siyuan sighed, glanced at He Xiaobei who was playing in the yard, and said with a smile, "Look, Mianmian was the first to give birth to a child in a few of us, so that's it. The people they knew together were nobody but Zhou Siyu, so everyone thought of Zhou Siyu first. The two looked at each other, and then looked at Lu Siyuan in unison. Shen Mianmian and Yang Xiaoxi said in unison. As soon as he sat down, he deliberately sold out, "Guess who I met abroad." After returning home, he went directly to Shen Mianmian's place. Lu Siyuan returned to China after staying abroad for more than half a month. The two silently reached a consensus and decided to slowly get better in a foreign country together. Hearing the birth of children, Zhou Siyu was not very happy but also knew that having more children was indeed a way out. In another ten years, when the children are older, life will not be so hard." Zhao Xinlan glanced at Zhou Siyu "You'd better have a few more babies, so that no one can bully us with the support of children in the future." "I have four children now, and five are born in my stomach. "Okay, then we'll raise our children together and battle wits with them."
